As CIO for global business services and finance technology at Deutsche Bank, Marc Earl is responsible for the organisation's technology platforms to help cope with increasing volumes of financial transactions. This is the second consecutive year that he's made the CIO50 list.

One of Earl's main challenges is to keep the platform as reliable and efficient as possible to maximise throughput and minimise costs. He also helps with innovating around new products and markets.

Earl has recently been given the task of creating a cross-bank production management division and is a member of Deutsche Bank's IT and operations management committee.

Earl has worked in the financial sector for 27 years. Prior to joining Deutsche Bank, he held numerous roles including programme and project manager for a major financial software house, head of capital markets at BNP Paribas, and CEO of a software testing and quality assurance consultancy.
